of a 400 kW RTSPV system installed at the Jawaharlal Nehru National College of Engineering (JNNCE), located in Shimoga, Karnataka. The system, operational since its installation, provides clean energy to the college campus, reducing its carbon footprint and contributing to sustainable energy use. The performance of the system is evaluated by analyzing key parameters such as energy generation, efficiency, capacity utilization, and the overall economic benefits accrued from the integration of the solar system into the college’s power grid [5]. The primary objective of this analysis is to assess the operational efficiency and reliability of the RTSPV system over time, with particular emphasis on understanding its energy production patterns, system losses, and impact on electricity consumption. Additionally, the study aims to identify any challenges faced during operation, such as performance degradation or maintenance issues, and offer recommendations for optimizing the system’s performance in future installations. The findings of this analysis can serve as valuable insights for academic institutions, government bodies, and industries looking to adopt similar solar energy solutions to meet their power needs while promoting environmental sustainability [11].
Demand for electricity and energy bills is continuously increasing every year due to the rise in connected loads at the campus and the increase in energy cost per unit from the supply company. This paper presents a comprehensive performance analysis of a 400 kW Rooftop Solar Photovoltaic (RTSPV) system installed at JNNCE Shimoga, Karnataka. The study evaluates energy generation, system efficiency, and economic viability over a defined operational period. To meet the electricity needs of the JNNCE campus, reduce carbon emissions, and provide a practical learning facility for students in solar photovoltaic system a 400kW capacity roof-top solar PV system (RTPSV) has been installed. The study yields the result that the installation of a 400 kW Roof Top Solar Photo Voltaic system produces 4,68,370 units of electrical energy per annum. JNNCE consumed 5,59,795 units per annum. The solar power plant produces 83.66% of the electrical energy required by JNNCE. To meet 100% electricity from solar power plant 64 kW solar plant is to be added, which produces revenue of Rs 7,77,100 per year, Rs 31,74,000 investment required to install additional plant. The payback period for the additional plant will be 4 years 1 months. additional plant generates a savings of Rs 1,63,19,325 in its life time. Performance of the solar PV system before and after cleaning the panel is also determined, 0.4% of efficiency of the solar plant increases due to the cleaning of solar panel twice in a month.
Methodology: The case study of 400 kW rooftop solar photovoltaic system involves data Collection, data analysis, performance analysis and performance evaluation by experimental method. The hardware components installed are examined onsite and following data is collected:
Key words: Solar PV System, CO2 Emission, Payback Period, Performance Ratio.
Introduction: The increasing demand for renewable energy sources, coupled with the growing concerns over environmental sustainability, has led to significant advancements in solar energy technologies. Among these, rooftop solar photovoltaic (RTSPV) systems have gained substantial popularity due to their ability to harness solar power directly from buildings, offering a decentralized, clean, and cost-effective energy solution [1]. In India, where solar energy potential is abundant, the installation of largescale RTSPV systems has become a key strategy to reduce dependency on conventional fossil fuels, lower greenhouse gas emissions, and address the country’s rising electricity
